Answer:
This can be solved by using the empirical rule for a normal distribution.
Step-by-step explanation:
A. The number of skateboards given is one standard deviation above the mean. Approximately 68% of the data points lie within the range plus and minus one standard deviation of the mean. Therefore the required percentage is:
68 + 16 = 84%.
B. The given number of skateboards is two standard deviations above the mean. Approximately 95% of the data points lie within the range plus and minus two standard deviations of the mean. Therefore the required percentage is:
5/2 = 2.5%
C.The given number of skateboards is one standard deviations below the mean. Therefore the required percentage is:
16%.
No, not all of these questions are statistical.
The first question does Mary like snacks is a Yes or No question which doesn't provide any statistics.
Answer: cools rapidly
Step-by-step explanation:
Some igneous rocks contain crystals of very different sizes. These
rocks formed from magma that started cooling within Earth and then
erupted onto the surface. The large crystals grew as the magma cooled
slowly. The small crystals grew as the lava cooled quickly.
Hope this helps!
